Recently, MNAC (NMCA-National Museum of Contemporary Art) and the Royal Netherlands Embassy organised a debate about the public space; Justin Baroncea presented the case of public spaces in Barcelona at zeppelin; I talked about this under the Revival of the Fittest conferences organised by Hydrasociety. Briefly, there are many actions dedicated to this topic; some of them not only by our team, in which we talk increasingly often about what and how it should be done and I had the feeling that this is for everybody something quite obvious. Despite that, I realise there are confusions for specialists as well, be they architects or great urban planners. Since the value of the public space and how this should be designed, created, developed is not clear within our own profession either. Perhaps that many of the things to come up in these pages are or will be signed by architects, artists or designers.
